CONSTRUCTION OF GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 659,843, dated. October16, 1900.

' Application filed April 26,1900. Serial No. 14,484. (No model.)

To ztZZ whom, it may concern.-

Be it known that I, GEORGE BRAY, a subject of the Queen of Great Britainand Ireland, whose postal address is Bagby Works, Leeds, in the countyof York, England, haveinvented certain new and useful Improvements inthe Construction of Gas-Burners, (for which I have applied forprovisional protection in Great Britain, No. 6,361, dated April 5,1900,) of which the following is a specification.

This invention has for its object the construction of that class ofgas-burners in which a diminisher is introduced; and the object of theinvention also is to secure the diminisher within the burner-socket insuch a manner that a gas-tight joint is made between the diminisher andsocket and to so form the said joint that on nipping the exteriorof thesocket the liability of damaging the diminisher is reduced and thegas-tightjoint preserved should the contour of the socket be to someextent disturbed on screwing the burner into or out of the gasfitting.Hitherto diminishers have been placed within the burner-socket, and thejoint between the exterior of the diminisher and interior of the sockethas generally been made with cement of the consistency of paint, theresult being that the diminisher is rigidly held in its position, sothat on nipping the exterior of the socket when screwing the burner intothe nipple of the gas-fitting should the burner-socket become distortedthe circumferential joint of the diminisher is broken, thus allowing gasto pass, or in some cases the diminisher is fractured, thus destroyingthe efliciency of the diminisher and resulting in a waste of gas.

In order that my invention may be thoroughly understood, I will describesame by making reference to the accompanying drawings, in which- Figure1 represents an elevation of a gasburner socket suitable for having myimprovement applied thereto. Fig. 2 is a plan of a diminisher-suitablefor introduction within the burner-socket. Fig. 3 is a sectionalelevation of same. Fig. 4 is a vertical section through a gas-burnerarranged in accordance with my invention. Fig. 5 is a plan of a cup usedfor making the joint between the diminisher and burner-socket, and Fig.6 is a section through the said cup.

Similar letters indicate similar parts Where they appear, and all theviews are drawn to an enlarged scale for more clearly showing theconstruction.

The metal socket of the burner is indicated by the letter A and isthreaded at B for screwing upon the gas-fitting and may be provided witha union jet-tip O, as shown.

In carrying out my invention in order to avoid the before-mentioneddefects I form a cup D, of yielding material-such as, for example,cardboardthe cup D having a hole E through the base of suitablediameter, so as not to interfere with the passage of the gas, and intothe cup D is placed a diminisher F of ordinary configuration. These arepressed into the interior of the socket A, the cup D, of cardboard orother suitable yielding material, supporting the diminisher F, thusforming a gas-tight joint around the same. It will thus be seen that onsubjecting the exterior of the gas-burner socket A to the necessarypressure required on the use of the pliers to screw the burner into thefitting the joint, being of the nature of a cushion, yields and protectsthe diminisher F from breakage or deformity and at the same timepreserves a gas-tight joint.

What I claim as my invention is In combination with the burner-socket A,threaded to engage with a gas-fitting, the op posite end of said socketprovided with a tip 0, a diminisher F, placed within a cup D of yieldingmaterial applied within the socket A, substantially in the manner asshown and described and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twowitnesses.

GEORGE BRAY.
